5.8.3 Current Control Mode Selection

This function reduces high-frequency noises while the linear servomotor is being stopped. This function is
enabled by default and set to be effective under different application conditions.

5.8.4 Current Gain Level Setting

This function reduces noises by adjusting the parameter value for current control inside the SERVOPACK
according to the speed loop gain (Pn100). The noise level can be reduced by reducing the current gain level
(Pn13D) from its factory setting of 2000% (disabled). If the set value of Pn13D is decreased, the level of noise
will be lowered, but the response characteristics of the SERVOPACK will also be degraded. Adjust the current
gain level within the allowable range at which SERVOPACK response characteristics can be secured.

5.8.5 Speed Detection Method Selection

This function can ensure smooth movement of the linear servomotor while the linear servomotor is running.
This function is disabled by default. Set the value of Pn009.2 = 1 to enable this function.
When the linear scale pitch is long, noise produced while the linear servomotor is running can be reduced by
using this function.

• If the parameter setting of the current gain level is changed, the responsiveness char-
acteristic of the speed loop will also change. The servo must, therefore, be readjusted
again.
